Tips to Make Your Deck aSuccess

PlanningPlan your deck project well ahead of time and makesure all materials for construction and finishing are onhand. Carefully lay out your deck area using string tobe sure that it is square and level. Please note: Dyelots vary from roll to roll. Please be sure of dye lotnumbers, or use material from one roll of vinyl. If more than one roll is needed, a special order may be necessary. Use the 3 - 4 - 5 squaring trianglemethod as shown in the deck diagram on this page. Besure to factor in slope to prevent water from pooling onthe deck. Proper drainage is necessary.

Preparation Make sure your site is as level as possible. Remove allorganic material from the area. If deck is within 18” ofground, a vapor barrier is required.

Attaching the Ledger Position the ledger level at 2 1/2” below the threshold.You may have to remove the siding to provide a flat,square surface. Take care to plan the location of thefasteners and lags so they do not interfere with joisthangers. (Study the deck layout on this page).

Posts and Footings Review the joist/beam spacing and carefully locate thefooting holes before digging. Different regions have different requirements for depth. Check your local building codes. If you have a low elevation construction,it is acceptable to use pre-cast pier blocks and metalpost connectors as described in the drawings. Considerconcrete footings for higher elevation decks.

Posts and Beams Use a level on a string to find the correct beam heightto your posts. Cross check this height with a diagonalstring before trimming your post. Use metal post-beamconnectors if using a single beam (as in beam detail D).Be sure to have adequate slope for drainage (approximately 1” of slope for every 10’).

Joists Before attaching to the ledger; sight down eachjoist for the crown and place the crown up.Use a metal joist hanger at the ledgerand toe nail to the beam withgalvanized box nails. Besure to maintain uniform spacing(16” on centre).Trim joists to length,keeping in mind the width of plywood and thewidth of thedek-master® vinyl.

T & GPlywoodDecking Exterior Grade select good one side 5/8” or 3/4” T&G sanded plywood; is required. To fasten the plywood, use treated deck screws.Coutersink screws just below surface. Screw sheetsevery 6” around perimeter and 12” spacing on the center joists. Stagger plywood sheets, leaving 1/8”expansion joints between the plywood sheets.

IMPORTANT: Blocking must be used under the plywood for any unsupported joints.

Flashing and CantstripA standard galvanized metal non-return flashing shouldbe installed around the outside deck perimeter. Installcantstrip 3/16” away from siding. Use 1” galvanizedring nails. Nail cantstrip and flashing every 6”. Installflashing 1/4” away from the edge of the plywood. Start to nail from the center of each piece and work to either end.

Measuringdek-master® vinyl Capri 31.5mil 74” *,dek-master® Provinyl Messina 45mil 74” *,dek-master® Pro vinylMessina 60mil 72” width. *May be special order items.As with carpeting, fewer overlap seams result in a better appearance. To determine the correct amountof vinyl sheeting required, allow for:

• Extra 2" down the flashing• Extra 11⁄2" up the cantstrip, (does not apply to 60 mil,)see separate instructions.• Extra 1" for each overlap of vinyl

Please note that 60 mil requires different instructions.Please see our 60 mil brochure or contact Ducan forproper instruction, or visit www.ducan.com.

Ducan recommends the seams run perpendicular tothe slope of the deck so the water runs away from theseam. It is however up to the homeowner to sketchaccurately and measure the deck in order to decide onthe most economical or aesthetically pleasing way tolay the vinyl.

IMPORTANT: In inclement conditions,the plywood must be kept dry. Make abarrier by suspending a tarp at least 24”from the deck surface. Hint: Use theroof fascia. Ducan does not warrantydek-master® on stairs. WHEN TO APPLY:Temperatures between 15C/60F and30C/85F are best.READ TIPS TO MAKE YOUR DECK ASUCCESS and ALL DIRECTIONS BEFOREBEGINNING. SEE WEBSITE VIDEO.This brochure is specific to 31.5 mil and 45mil vinyl. Please see our 60 mil brochure for 60 mil instructions or visit our website at ducan.comApplication Instructions1. Sweep deck thoroughly.2. Once cantstrip and non-return dripflashing have been nailed to the deck, fillall joints and surface imperfections and

transitionfrom flashingto deck with dek-master®

Dek-Patchjoint fillerand patchingcompound.

Follow mixing instructions on the label.3. The pattern of the vinyl is directional.Sheets should be positioned in the samedirection. Lay out dek-master® vinyl toensure the fewest possible seams. Startfrom the furthest point from the wall andallow enough vinyl to cover down the edgeof the flashing completely. Unroll the vinylsheet and adjust to ensure it is parallel tothe wall and/or deck edge. Tack within 1”of upper edge where the seam will be totemporarily hold it in place .

4. Fold vinyl sheet back half its width plus6” (as shown above) apply dek-masterAdhesive to the back of the vinyl (fuzzyside) first, then the deck surface. Besure to get adhesive on the underside ofthe fold area using a paint brush if needed. The areas where the vinyl willgo down the flashing/canstrip do notrequire waterbased or low temp. adhesive. This area will be done laterwith Trim Adhesive.Please note: Water based adhesive doesnot adhere to metal flashing and cant strip.Use Trim Adhesive on flashings and verticle surfaces.IMPORTANT: Both surfaces must have acomplete even coat of adhesive.Let the adhesive become tacky. Test thetack by placing your finger to the

adhesivecoated backside (fuzzyside) of thevinyl.

5. Gently unfold adhesive coated vinylsheet onto the deck surface by workingfrom the middle point to the edge of thedeck, then outwards to the ends. Let thevinyl fall naturally, do not pull or forcethe vinyl into position. This can causestretching. The vinyl has a memory andif stretched, may pull back to its originalstate by pulling away from flashing,and/or the overlap seam. Ducan recommends using your hands tosmooth the vinyl down. If a bubble formsin the vinyl, smooth it out with your palmsto remove it.

6. Remove tacks and fold the vinyl sheetback as shown. Apply dek-master®

Adhesive to back of vinyl first, then tothe deck surface. IMPORTANT: Both surfaces must havea complete, even coat of adhesive.

7. Repeat step 5.

8. Subsequent vinyl sheets must beoverlapped 1” to the adhered vinylsheets. To prepare subsequentsheets, place a piece of 1” maskingtape to the underside edge where theoverlap will be and to the finishededge see above. It is necessary to follow this step to ensure the RegularAdhesive does not interfere with the Overlap Cement. Remove this masking tape, once the vinyl hasbeen glued down, prior to usingOverlap Cement.

1. Applying Overlap CementNote: Overlap Cement cannot be used with60mil vinyl.

Remove all previous masking tape.Temporarily apply 1” masking tape 1/16” awayfrom overlapping edge. This is to catch theexcess Overlap Cement but also leave a slightline of Overlap Cement to create a moistureproof barrier. Extrude a 1/4” bead of OverlapCement 1/2” under the overlapped edge.Using the Ducan seam roller on the overlap,apply pressure lengthwise, then crosswise, squeezing some of the Overlap Cement frombeneath the seam onto the masking tape.

IMPORTANT: To ensure the overlap bond issecure, look eye level to the edge of the seamto make sure there is a water tight seal. Acove should be present on the overlap edge.(There should be no voids where moisture canpenetrate under the seam). Add more OverlapCement if needed. NOTE: Do not useexcessive pressure with the seam roller asthis could distort the vinyl layer. Only a 1” overlap is required. Making the overlap largerwill not allow Overlap Cement to work satisfactorly.

Remove masking tape. Draw excess smooth.As an alternative to Overlap Cement, hot airwelding seams is an option for the 45mil, butis a requirement for the 60mil. Ducan offersthe hot air welder along with a DVD for thosewishing to do this method. Please contactyour retailer or Ducan Customer Service 1-800-943-8226 for rental of this unit.

2. Finishing Cantstrip Ensure the vinyl is completely adhered to thecantstrip by using dek-master® Trim Adhesive, aspecially formulated exterior contact adhesive forvertical surfaces, and then with a razor knife, trimvinyl to 1/4” – 1/2” above the cantstrip. Tuck theextra vinyl down between the wall and thecantstrip and caulk using dek-master® caulking.

Tip: If dek-master®caulking is not available, an outdoor polyurethane caulking may be substituted.

IMPORTANT: Do not use silicone or latex basedcaulking as they are incompatible.

3. Finishing Outside CornersAt the outside corners, cut the vinyl from the

outside edge to the deck corner in line withone edge (See photo 3). This will be foldedover and Overlap Cement will be applied afterthe vinyl has been adhered to the flashing.

Using a paint brush, adhere the vinyl to theperimeter flashing with Trim Adhesive. Avoidapplying Trim Adhesive to the area where theOverlap Cement on the outside corners will beapplied. When all the vinyl has been adhered tothe flashing, trim the vinyl to the bottom edge ofthe flashing using a utility knife.

Fold the vinyl corner flaps one on top of theother to form a seam line that is directly verticalto the actual edge of the deck corner. ApplyOverlap Cement to the underside of this flap androll with the seam roller until firmly adhered.

Starting at one end of the U-Channel Trim, clip it onto the bottom of the flashing. (See photo 4). For directions on how to go around corners with the U-Channel, please see our instructional video online at www.ducan.com.

TIP: Apply beads of Overlap Cement every 4” to 6”inside the U-Channel canal to chemically weld it tothe vinyl covered flashing.

Helpful Hints• Household wax paper can be used to prevent the adhesive from accidentally being applied onto the top side of the vinyl surface. It can be used while rolling over the overlap seam or used against the siding during application.• Avoid getting adhesive on the vinyl surface. If accidents do occur, cleanthe spills with a clean damp cloth. Warning: DO NOT USE SOLVENTS. THISWILL RUIN THE VINYL SURFACE. Please see our website FAQ’s or callDucan for further instruction if needed.• When the vinyl is folded back half its own width plus 6”, place cansevery 5’ on leading edge. This will prevent curling while the adhesive isbecoming tacky.• Depending on temperature and humidity, the Regular Adhesive can takelonger to dry. Complete the deck as directed and in time the adhesive willdry.• Allow only light traffic for the first 14 days, while the adhesive cures.• The vinyl membrane will pull back to its original composition if stretched. Do not pull or stretch the vinyl.• Use Trim Adhesive for all vertical applications.• For 60 mil application, please see our 60 mil instructions.
